SPECIFICATION forming part of Letters Patent No. 689,081, `datedDecember 1'7, 1901.

Application filed July 2, 1901. Serial No. 68.840. (No model.)

To aZZ whom it may concern.-

Be it known. that I, EYVIND LEE HEIDEN- REICH, a resident of Chicago, inthe county of Oook, State of Illinois, have invented certain new anduseful Improvements in Fireproof Roofs, dac., of which the following isa full, clear, and exact description.

This invention has for its object more particularly to provide animproved construction of plate whereby roofs, ceilings, dac., may beformed; and the invention consists in the features of improvementhereinafter described, illustratedin the accompanying drawings,and moreparticularly pointed out in the claims at the end of this specification.

Figure lis a view in vertical section through a roof embodying myinvention. Fig. 2 is a view in crosssection online 2 2 of Fig. l. Fig. 3is an enlarged detail view in cross-section, showing the abutting endsof two roof-plates interlocked with a supporting-beam. Fig. et is adetail perspective View of one of my improved roof-plates. Fig. 5 is aview showing one edge of the improved roof-plate. Fig. 6 is an enlargeddetail view showing the manner of connecting the sides of theroof-plates together. Fig. 7 is a detail view of one of theridge-plates.

A designates the I-beams of the roof, which may be arranged in usual orsuitable Inanner. Across these I-beams extend channelbeams B, that aresecured to the I-beams and are preferably U-shaped incross-section, asshown. My improved construction of roofplate will rest upon thechannel-beams and will be interlocked therewith, as will presently morefully appear. In the preferred form of the invention the plates thatcornprise the body of the roof are of substantially the shape andconstruction shown in the drawings-that is to say, each of these platesC has one of its ends formed with a reverted edge c, adapted to engagethe flange of one of the channel-beams B, as clearly shown in Figs. land 3 of the drawings. This end of the plate C is preferably beveled, asat c, above the reverted end c, so as to receive thecorrespondingly-beveled end c2 of the adjoining plate. Each of the mainplates being thus formed with a reverted end and with its opposite endbeveled, .the plates can be interlocked with the supporting-beams andcan be engages the reverted end c of the plate.

set together, as clearly shown in Figs. l and 3 of the dra-wings.

In order to enable the plates C to be securely joined or interlocked,each of these plates is formed with offset flanges c3 and ciL at one ofits edges, these iianges c3 and c4 forming between them a channeladapted to receive the plane edge c5 of the next adjoining plate. (SeeFigs. 2 and 6.) The flange c3 upon the under side of each plate iscutaway at its ends, as seen in Fig'. 3, in order to permit the platesto be set in position upon the beams. Thus by reference to Fig. 3 itwill be seen that in order to permit the reverted edge c to be hookedover the upper flange o of the channel-beam B the end of the plate-Hangsc3 must be first brought close to the back of the channel-beam and willthen be drawn away therefrom as the flange b of the beam In placing theplates in position a layer of cement CZ will preferably be interposedbetween the anges b of the channel-beams and the engaging ends c of theplates. So,also,a layer of' cement or mortar cl will be placed betweenthe beveled portion c of the plate and the correspondingly-beveledportion c2 of the adjacent plate. A layer of cement or mortar d2 willalso be placed in the joint between the lianges c3 and c4 of the platesand the edge c5 of the adjoining plates, that are received between theseflanges. From this construction it will be seen that each of theroof-plates will be securely locked to the cross-beams or channel-beams,and the plates of each row will have their side edges firmly lockedtogether.

In Fig. l of the drawings is shown the preferred manner of forming theridge of the roof. This ridge will consist of angular ridge-plates E,each of which will bemolded with the ribs e, adapted to t over thetransverse ribs c6, that will be formed adjacent the upper end of suchof the plates O as will be located immediately next to the ridge of theroof. At the ends the ridge-platesE will be formed with the iianges e2and e3, forming a channel to receive the edge of the adjoiningridge-plate, and each of the ridge-plates will preferably be providedwith a metal stay- -frame consisting of intersecting wires, thisstay-frame extending into one of the [ianges at the end of theridge-plate.

IOO

In practicing the invention the plates C Will preferably be molded ofmortar or like plastic material, and in the process of molding theplates there Will be embedded in each of the plates a metal stay-framethat consists, preferably, of transversely-disposed Wires f and f. Byreference to Figs. l and 8 it Will be seen that these wires are moldedin the reverted ends c of each plate, thereby giving great strengththereto and-enabling the plate to securely engage the supportingchannelbeam beneath it. It will also be seen that each of the metalstay-frames is extended into the beveled end c2 of each plate, therebygreatly enhancing the strength of such portion of the plate. The featureof forming plates from plastic material havingstay-wires embeddedtherein is not novel; but I believe my present invention presents thefirst instance of a plate formed from plastic material and having areverted end, suitable metal stays being embedded in said plate and insaid reverted end portion. The terms reverted end and reverted edges asherein employed are not intended to limit the invention to the precisedetails set forth, since manifestly the extent to which the ends oredges are turned inwardly or reverted from the body of the plates is notessential.

One great advantage incident to the construction above described is thatthe plates being formed in section can be made at a distance from theWork (and hence under cover and in any kind of Weather) and can bequickly set in place with but very little trouble and expense. l A roofembodying this invention will be found particularly advantageous forfactories, rolling-mills, steel-mills, and the like, Where the gasesincident to the Work being done would ordinarily tend to speedilydestroy the corrugated-iron roofs commonly employed in such situations.

Vhile the improved plates above described are more particularly intendedfor use in the construction of roofs, it is manifest that such platesmay also be advantageously used in forming ceilings, partitions, or likeparts of iireproof structures. The ridge-plates E may be used forgutters and will be found particularly applicable Where gutters areinterposed between the eaves of twoladjoining roofs. In such case theridge plates E will simply be inverted. It Willbe readily understoodthat Where special shapes are required for conductors, gutters, &c.,these may be easily molded and placed in position.`

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. Aplate for roofs, dac., formed from plastic material and provided atone end with an angularly-extending or offset portion adapted to engagea supporting-beam and a metal frame or stay embedded in said plate andin said angular or offset portion that engages said supporting-beam.

2. A plate for roofs, &c., formed from plastic'material and having areverted edge, said plate having embedded therein a metal stayframeextending around said reverted edge.

3. A plate for roofs, dac., formed from plastic material and having areverted edge With a beveled upper surface.

4. A plate for roofs, dac., formed from plastic material having one edgereverted and beveled upon one side, the opposite end of said platehaving its edge oppositely beveled.

5. A plate for roofs, dac., having one of its edges beveled and revertedand having its opposite edge beveled and metal stays extending aroundsaid reverted edge and into said opposite beveled edge.

6. Aplate for roofs, dac., formed from plastic material and provided atone end with an angularly-extending or offset portion adapted to engagea supporting-beam and having its edges cut away to engage the edges ofthe adjoining roof-plates and a metal frame`or stay embedded in saidplate and in said angular or oset portion.

7. A iireproof structure comprising metal supporting-beams and bars andplates formed of plastic material having angularly-extending or offsetportions adapted to engage said supporting bars, said plates havingtheir edges cut away to receive the edges of adjoining plates and metalstays or frames embedded in said plates and extending into their angularor offset portions and into their cutaway edges.

8. A roof for fireproof structures comprising metal supporting-beams andbars and plates of plastic material, said plates having theiroverlappingends arranged opposite said supporting-bars and having angular or offsetportions adapted to engage said supportingbars, and metal frames orstays embedded in said plates and in their overlapping ends and angularportions.

9. Aplate for roofs, dto., formed from plastic material havingoppositely-oset flanges at one of its edges to form a channel to receivethe edge of the adjoining plate, and metal staysl embedded in said plateand extending-into one of said offset iianges.

10. A plate for roofs, dto., formed from plastic material having oneedge provided With oifset ilanges forming a channel at said edge toreceive the edge of the adjoining plate, one of said edge flanges beingshorter than the body of the plate to permit the interlocking of saidreverted edge of the plate with the sustaining-beam.

Il. A roof for fireproof structures, compris-` ing metal beams and crossbeams or bars and roof-plates formed of plastic material havinginwardly-turned edges to interlock with said cross beams or bars, saidplates being provided with suitable metal stays and the edges of theplates being interlocked together.
